Monoprice Blackbird 4K HDMI Extender | 4k HDMI extension to 164 feet, Bi-Directional

Purchased this to replace an HDMI extender that was not powered and quit working. I'm not sure if the extender went bad after 9 years or with higher definition signals I needed a powered extender but I thought I'd give it a try and it works perfectly now. I also like the HDMI pass through which allowed me to connect a second TV and eliminate the need for a separate cable box. The only negative is that if you had both TV's on they have to be tuned to the same channel, but this isn't an issue for me as rarely would have both of the TV's on at the same time because of where they are located in my house.

Good product and works well, I have not checked the max distance it works

Works fine -absolutely no problems. Mounting brackets are a plus.

It seems like these boxes go out of sync and stop transmitting. I would ask for a refund and go with HDMI over IP system instead. It's been consistent where I'll change to the HDMI input these are suppose to send image to and need to power cycle the boxes to bring back the video feed. Disappointing overall. Good image when it works but IRRITATING reliability.

We had to replace what we had originally due to buying a 4k TV. The original require 2 Cat5 or 6 cables, this does not. Once hardware is in place and cables attached, it worked with no issues. Picture is great and we have not had any connection or other issues at all.

Although the unit is very light, in a mission-critical environment you/we need to secure everything. There are no holes or bracket to do so. Instructions incorrectly state that both receiver and transmitter need to connect to an AC/DC adapter. They do not. In fact, the package only includes one power adapter.

Hit or miss, functionality. But when it works it's great

Works great - great price - easy to install. What’s not to like?
